SDI Dual Rate Shock Spring Kit for Polaris RZR XP 1000 (2-Seat)
Product Description
The SDI dual rate shock spring kit for Polaris RZR XP 1000 two-seat models is designed to significantly improve suspension performance, stability, and ride comfort. After extensive testing and tuning, SDI engineered this kit to convert the factory suspension into a true dual-rate spring system that uses both tender and main springs throughout the suspension travel.
Dual-rate spring setups allow the suspension to absorb small bumps more smoothly while providing additional support during larger impacts. This results in improved ride quality and better suspension control across rough terrain.
The SDI spring kit helps reduce body roll, nose dive (bucking), and harsh bottom-outs (G-outs), giving your RZR improved stability during aggressive driving and high-speed terrain.
Each kit includes durable motocross-inspired crossover rings designed for easy adjustment and installation. These rings allow riders to fine-tune when the secondary spring engages, helping dial in suspension performance for different terrain and driving styles.
Built using high-quality materials and manufactured in the USA, the SDI shock spring kit is designed for long-lasting durability in demanding off-road conditions.
